If he could reach a table in the restaurant unsuspected success would be his.
只要他能走到餐桌邊不引人生疑，那就是勝券在握了。

【解析】這句話是一個(gè)由if引導(dǎo)的條件狀語從句，表示在某條件下，某事很可能發(fā)生。翻譯成“如果......就......” “只要......就......”。

       If you ask him,he will help you．

       如果你請(qǐng)他幫忙，他會(huì)幫你的。

 
       If you have finished the homework,you can go home．

       如果你作業(yè)做完了就可以回家了。

另外，if從句還表示一種虛擬的條件或假設(shè)。從句多用一般過去時(shí)或過去完成時(shí)，表示對(duì)現(xiàn)在或過去的一種假設(shè)。

       If I were you，I would invite him to the party．

       如果我是你，我會(huì)邀請(qǐng)他參加聚會(huì)。

 
       I would have arrived much earlier if I had not been caught in the traffic．

       要不是交通堵塞，我本會(huì)來得早一些。

我們可以把if 條件句的時(shí)態(tài)搭配總結(jié)如下：

1．if從句用一般現(xiàn)在時(shí)，主句用一般將來時(shí)

       If he runs he’ll get there in time.

       如果他用跑的，他就會(huì)及時(shí)趕到那兒。

2．if從句用一般現(xiàn)在時(shí)，主句用may/might/can

       If the fog gets thicker the plane may/might be diverted.

       如果霧在大一些，飛機(jī)可能就會(huì)改在別的機(jī)場(chǎng)降落。

3．if從句用一般現(xiàn)在時(shí)，主句用must/should

       If you want to lose weight you must/should eat less bread.

       如果你想減肥，你必須少吃面包。

4．if從句用一般現(xiàn)在時(shí)，主句用一般現(xiàn)在時(shí)

       If you heat ice it turns to water.

       如果把冰加熱，它就會(huì)化成水。
